Hi all I am using cpan Net::LDAP module to access LDAP entries. I want to search LDAP entries using Net::LDAP search method. When I do search, I want some limited number of entries from search result, for this(searching) process I am using Net::LDAP::Control::VLV module. But I get error on VLV response control. Please, any one have idea about this error. * Error:* Died at vlv.pl line 50, This is my example. I changed the font style of line 50 #!/usr/bin/perl -w use Net::LDAP; use Net::LDAP::Control::VLV; use Net::LDAP::Constant qw( LDAP_CONTROL_VLVRESPONSE ); use Net::LDAP::Control::Sort; sub procentry { my ( $mesg, $entry) = @_; # Return if there is no entry to process if ( !defined($entry) ) { return; } print "dn: " . $entry->dn() .
